Apparatus for coating a profile surface, and coating method thereof

Abstract

The present invention relates to an apparatus for coating a profile surface with metallic texture paint by roll coating in combination with spray coating, and a method for coating thereof. The first major feature of the present invention is an apparatus for coating a profile surface, characterized in that it is provided with a roll coater for roll coating at least one surface of profile with a UV paint served as a binder, and a spray coater, installed at a position next to the roll coater, for spray coating with a metallic texture paint comprising a solvent, acrylic beads and metal powders on the coating layer of UV paint. The second major feature of the present invention is a method for coating a profile comprising the steps of roll coating at least one surface of profile with a UV paint served as a binder, and spray coating with a metallic texture paint containing a solvent, acrylic beads and metal powders on the coating layer of UV paint.

Description

[0001]This application claims the benefit, of the filing date of Korean Patent Application No. 10-2006-0099817 filed on Oct. 13, 2006 and Korean Patent Application No. 10-2007-0017551 filed on Feb. 21, 2007 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.TECHNICAL FIELD[0002]The present invention relates to an apparatus for coating a profile surface with metallic texture paints by a roll coating in combination with a spray coating, and a method for coating thereof.BACKGROUND ART[0003]Generally, window materials of synthetic resins are prepared by extruding profiles, whose surfaces are almost color coated with white paints. Therefore, when windows are prepared from these materials and installed in buildings, the white exterior structures are displayed. Since these window materials have a single color, persons have generally feelings weaker than those of windows prepared by metal materials, when they view building...

AI Technical Summary

Benefits of technology

[0014]In the apparatus for coating the profile surface according to the present invention, a splash prevention means can be positioned right below the spray coater and can absorb the metallic texture paint sprayed from the spray coater for preventing the metallic texture paint to be splashed. Here, tray filled with water can be used as the splash prevention means.

[0015]The apparatus for coating the profile surface of the present invention may further comprise a scatter prevention means, installed below the spray coater, and absorbing the metallic texture paint sprayed from the spray coater for preventing the metallic texture paint to be scattered around.

[0017]In the apparatus for coating the profile surface according to the present invention, a filter for filtering paint can be installed between the second paint receiver and the discharge pump and a shield plate can be installed below the spray coater for preventing the non-coated side of the profile from being coated with the metallic texture paint.

Problems solved by technology

Since these window materials have a single color, persons have generally feelings weaker than those of windows prepared by metal materials, when they view buildings outside.

Therefore, aesthetic properties may be scarce, including surface texture and brightness.

In addition, since paints have long curing times, curing works take much time and thus mass productivity is restricted.

However, no coating apparatus and coating method has been proposed, providing a metallic texture with surfaces of window materials by simultaneously using a spray coating method and a roll coating method.
